What is the best audiophile speaker for a tiny square room?

my dedicated music room is a pretty reflective cube, 11x11x11. with a carpeted floor, no treatment.  I have two different systems that work great in that room.  First is my PrimaLuna DiaLogue HP (75 watts of tube power with the stock tubes) powering my Focal Diablo Utopia III's with the Focal Stands, through an MSB Analog DAC.  The Focal's are about 2.5 ft from the back wall, 8 ft from my listing chair.  Sound fantastic.  

The second system is Joseph Audio Pulsars, powered by a highly modified Plinius SA 100 Mk. III by Galbo Audio Designs, which also sounds fantastic.  I keep going back and forth on which I prefer.  Neither is really "better," just different.  I use a REL subwoofer with both systems. I would highly recommend either choice for a small room.  The Focal's are less forgiving on crappy recordings, while the the Pulsars have more bass and are better with bootlegs and that sort of thing but not as good on well-recorded stuff.  But it is a minor difference.  I am happy with both, so its hard to decide which to part with!

I have used small Totem speakers in small rooms, they are very musical  !

Good luck.I am simply stunned you can listen to those speakers in a room of that size. I had Martin Logans for 16 years and they HAD to be pulled about 6 ft from the rear wall to enjoy what they could do. I'm not sure how you managed it but congrats, I guess. They are spectacular speakers, no doubt in my mind!

@chungjh Did you come to a resolution to your speaker and room issues?

My floor standers in the same size room as yours are sounding amazing with the recently implemented DRC.  So good in fact that I bought a second amp yesterday to run as mono block, a Benchmark AHB2. I can make my speakers sound even bigger and more dynamic with more power (I tested this out). I have a second DRC implementation (another Convolution file) that I will use to deal with the additional bass from the additional power. All of this is done digitally on ROON (or JRiver) before the bits hit my DAC.

A lot of misinformation on this forum on DRC and I am glad I did more research and tried it out. A lot of info on this on AudiophileStyle and AudioScienceReview (ASR). I do not have any DRC involved on my Tuner or SACD player but I play those are mainly used on headphones.

A few years ago the founder of ASR, Amir, posted to me on a thread that I have to use DRC in any room. I thought he was a little over the top on that. Today, I am thinking he knew what he was talking about.
